Why the Bare Structure Needs Its Own Crew
Hang new drywall over sooty, smoky studs and the smell comes back through the paint on the first warm day. This stage decides whether your rebuilt rooms smell fresh or smell burned for years.
Licensed & Insured Independent Pros
Each contractor on our referral list is an independent, licensed and insured local company. Verify both, and ask whether the crew follows the IICRC S700 standard for fire and smoke work.
Upfront Written Estimates
Media blasting depends on square footage, the media used and how hard the space is to get into. Get a written, itemized estimate in hand before any blasting begins.
Rapid Local Dispatch
A real person answers around the clock, and the search for a crew begins on that call. Timing depends on which crews near Appleton are free, and it is often the same day.
Blasting Rigs and Probing Tools
Structural crews bring soda blast pots, dry ice units, big compressors, HEPA vacs, air scrubbers and a sharp awl to test every member.
Stay out of a fire-damaged attic, and never walk a charred roof deck to check it. Weakened joists and burned-through sheathing can give way without warning, and exposed wiring may still be live. Wait for the contractor to check that the structure is safe, and keep people off floors that sit over a burned crawlspace or basement.
Cleaning the Building From the Roof Deck Down
This is not contents cleaning and it is not debris haul-out. It is the work done on the wood, block, brick and steel that hold your house up.
Char Depth Probing and Member Decisions
An awl pushed into a charred stud tells the story: if it stops in sound wood after a thin layer of char, the member is usually a cleaning candidate. Deep char that eats into the section of a joist or truss chord means sistering or replacement.

- Photos of each marked member for the claim
Soda Blasting
Baking soda media knocks soot and surface char off framing while leaving the grain mostly intact. Expect fine dust and residue that has to be contained and HEPA vacuumed when the blasting is done.
Dry Ice Blasting
With dry ice the pellets sublimate on impact, so there is nothing left on the floor but the soot itself. It works well in tight attics and around wiring, though it costs more and is noisy.
- Hearing protection and ventilation required
- Good choice when residue would be a problem
Wire Brushing and Sanding
Small, isolated char spots are often handled by hand with wire brushes and sanders tied into a HEPA vacuum. Hand work is slower but sensible where a blast rig would be too much.
Brick, Block, Concrete and Steel Beams
Fireplace surrounds, block foundation walls and concrete slabs hold soot in their pores, and alkaline cleaners, scrubbing or blasting pull it out. Steel beams and columns are cleaned of soot and checked for warping or sag, which goes to the engineer.
Encapsulation and Attic Insulation Removal
Even well-blasted wood can hold faint odor in its pores, so crews roll or spray a pigmented shellac-based or specialty encapsulating sealer over cleaned framing. Attic jobs start by vacuuming out the smoky blown-in or batt insulation so the rafters and roof deck can be reached.
Crawlspaces get the same treatment on a smaller, dirtier scale: floor joists, sill plates and the underside of the subfloor are probed, blasted where needed and sealed. A smoke-stained or wet vapor barrier usually comes out and goes back new.
Ask your contractor which method they recommend for each area and why. A good crew may soda blast the open walls, dry ice the attic around the wiring and hand sand a few studs near the panel.
Plan for containment, because blasting throws soot and media into every corner it can reach. Expect poly over openings, taped-off HVAC returns and air scrubbers pulling the space under negative pressure during blasting. Ask how they will protect finished rooms and windows that were not damaged.

Phone the Dispatcher
Say which parts of the structure are open now, such as walls, attic, crawlspace, masonry or steel. Let us know if an adjuster, engineer or roofer has already visited.

Mobile Crew on Site
The contractor arrives with a compressor, blasting equipment and containment materials. First they confirm the roof deck and floors will hold weight and that the exposed circuits are dead.

Probe, Mark and Quote
Every exposed member gets probed with an awl and marked clean, sister or replace, and anything borderline goes to a structural engineer. A written, itemized quote covering area, blast method, encapsulant and attic insulation comes before any work starts.

Blasting, Sealing and Walkthrough
Once the wood is blasted, vacuumed and sealed, the crew lead walks you through the open structure. Smell the space on a warm day and get photos of each tagged member before anyone hangs drywall.

What Callers Said About Their Structural Crew
The attic fire left every rafter black and the insulation soaked. The crew pulled the insulation, dry ice blasted the rafters and rolled sealer on everything. Two rafters were cut deep enough that they called in an engineer, and those got sistered.
My contractor brother-in-law said all the black studs had to go. The crew lead pushed an awl into each one and showed me the wood was solid under a thin crust. They soda blasted and sealed them, and only three were swapped.
The fire in our lower level left the block walls and the steel beam coated in soot. The contractor cleaned the block and the beam, then had an engineer check the steel for warping. No smell now, even with the windows shut.
Your Structural Fire Cleaning Questions Answered
How do crews decide if a charred stud can stay?
The test is simple: they probe it. An awl or screwdriver pushed into the black surface shows how deep the char goes, and wood that is firm just under a thin crust can usually be blasted and sealed. Members with deep char, splitting or a lost cross section get sistered or replaced, and anything structural in doubt goes to a licensed structural engineer.
What is the difference between soda blasting and dry ice blasting?
Soda media is mild on the grain and helps with odor, though it leaves a white dust that needs a full HEPA cleanup. Dry ice pellets vanish on impact, so cleanup is easier and it works well around wiring, but it is louder and usually costs more. Many crews use both on the same house.
Why seal the framing if it has already been cleaned?
Wood is porous, and smoke molecules sit deep in the grain where no blasting can reach. An encapsulating sealer traps what is left so the odor does not seep back through the finished walls. Sealer only works over clean framing, never as a shortcut over soot.
Does the attic insulation have to come out after a fire?
If smoke reached the attic, almost always yes. Loose-fill and batts act like a giant filter for smoke, and hose water often soaks them as well. It is vacuumed out with an insulation vac so the rafters and roof deck can be probed, blasted and sealed before anything new is blown in.
Can soot be cleaned off brick and concrete block?
Usually yes, though masonry takes more effort than drywall because soot sinks into the pores. Crews use alkaline masonry cleaners and stiff brushes, and soda or other media blasting for heavy buildup. Spalling or cracked masonry is a structural question for a mason or engineer.
Do I need a structural engineer for fire-damaged framing?
You may not on a small job, but any doubtful load-bearing member calls for one. Trusses, beams, headers, steel and heavily charred joists are where an engineer's letter protects you and helps the claim. Your local building department may also require one before the walls close.
